TOP ROLL SADDLE.

SPECIFICATION forming part of Letters Patent No.75'7/72'7,

dated April 19, 1904;

Application filed October 16, 1902. Serial No. 127,548. mDdBL) To allwhom it may concern:

Be it-known that I, EZRA DIXON, a citizen of the United States, residingat Bristol, in the county of Bristol and State of Rhode Island, haveinvented a new and useful Improvement in Top-Roll Saddles, of which thefollowing is a specification.

This invention has reference to an improvement in the top-roll saddlesand weight-straps used on spinning-machines.

The object of the invention is to connect the weight-strap flexibly withthe saddle and provide means for adjusting the weight-strap on thesaddle. j

To this end the invention consists in the peculiar and novelconstruction more fully set forth hereinafter.

The top-roll saddles of spinning-machines have to be from time to timeremoved and the bearing-point of the strap readjusted to regulate thepressure of the front top roll on the sliver passing between the rolls.In this removal it is desirable to have the weight-strap flexiblyconnected with the saddle and to have means for accurately adjusting thebearing of the weight-strap on the saddle.

In my present invention I provide the front top-roll saddle with a slotand an adjustingscrew and provide the weight-strap with a contractedneck, by which the weight-strap may be flexibly secured with the saddle.

Figure 1 is an end view showing the front and rear top-roll saddlesbearing on the journals of the drawing-rolls and the front saddleprovided with an adjusting screw bearing against the weight-strap. Fig.2 is a top view, partly in section and on an enlarged scale, showing theweight-strap connected.

with the saddle and bearing against the end of the adjusting-screw. Fig.3 is a transverse sectional View showing the connection of theweight-strap with the front top-roll saddle.

In the drawings, (0 indicates the front toproll saddle; b, therearsaddle; c c, the top rolls; (Z, the weight-strap; a a slot extendingthrough the front top-roll saddle, and a a screw in screw-threadengagement with the front end of the top-roll saddle provided with thehead at The weight-strap is provided with the contracted neck cl belowthe head d and may beinserted into the slot 0, and then turned into theposition shown in Fig. 2, thereby connecting the weight strap flexiblywith the front top-roll saddle. The upper surface of the front top-rollsaddle is usually inclined toward the front, as is shown in Fig. 1, andthe weightstrap bears against the end of the screw a By adjusting thisscrew the weight-strap may be adjusted longitudinally on the saddlefarther from or nearer to the front top roll, and

thereby the pressure on the front roll may be regulated. The saddle maybe provided with the transverse ridge (4*, by which the turning of theweight-strap in the slot at is limited and the disconnection of theweightstrap of the saddle prevented.

In the ordinary or normal use, as shown in the drawings, theweight-strap cannot be removed from the saddle. even when the ridge 0*is omitted, because the head 0Z of the Weight-strap cannot be passedthrough the slot at with the screw a in the position shown in Fig.' 2. I1

By my improved construction of the front top-roll saddle and theweight-strap the position of the weight strap may be adjusted while thespinning-machine is in operation by inserting an ordinary screw-driverinto the slot in the head a and turning the screw.

As the bite of the front top drawing-rolls controls the delivery of thesliverto the spinning-spindle, the adjustment of the weight bearing onthe front top-roll saddle while the machine is running facilitates thecontrol of the delivery of the sliver, enabling the operator to changethe adjustment and watch the result of such change.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In a top-roll saddle, the combination with aweight-strap cl, the head (Z of the weightstrap and the contracted neck0Z below the head, of the saddle (0 provided with the slot (4, and thescrew (1 adapted to'adjust the position of the weight-strap, asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of. two subscribing witnesses. Y
